This is a basic Puppet module to install and set up cerebro.

Cerebro is an open source elasticsearch web admin tool built using Scala, Play Framework, AngularJS, and Bootstrap. Cerebro is the follow up project to Kopf- a popular elasticsearch web admin plugin.


Setup requirements

Cerebro >= 0.9.0 requires Java 11. This module does not attempt to install Java for you.

Beginning with Cerebro

This will install OpenJDK 11 and Cerebro version 0.9.4 with default settings.

# install java
package { 'openjdk-11-jdk-headless':
  ensure => present,

# install Cerebro with default values
class { 'cerebro': }

Advanced usage

Connecting to multiple pre-configured clusters

You can provide specific targets to connect to with an array of hashes:

class { 'cerebro':
  targets => [ { name => 'Production Cluster',
                 host => 'http://prod:9200',
               { name => 'Dev Cluster',
                 host => 'http://dev:9200',
               }, ]

Or, through Hiera and Automatic Parameter Lookup:

  - name: 'Production Cluster'
    host: 'http://prod:9200'

  - name: 'Dev Cluster'
    host: 'http://dev:9200'

Proxyserver settings

You can provide a proxyserver url and type to download the original package.

class { 'cerebro':
  proxy_server => 'http://proxy.localnet:8080',
  proxy_type   => 'https',

Limiting access with basic or LDAP authentication

You can require login with a basic challenge:

class { 'cerebro':
  basic_auth_settings => {
    username => 'admin',
    password => '1234',

Or through LDAP:

class { 'cerebro':
  ldap_auth_settings => {
    url           => 'ldap://ldapserver.localnet:389',  # can also be 'ldaps://ldapserver.localnet:636' for example.
    base-dn       => 'ou=active,ou=Employee,dc=example,dc=com',
    method        => 'simple',  # can be 'simple' ,'simple_tls' or 'start_tls'
    user-template => '',
    bind-dn       => 'cn=ldap_reader,ou=active,ou=Employee,dc=example,dc=com',
    bind-pw       => 'T0ps3cr3t!', 
  ldap_group_search_settings => {
    base-dn => "ou=active,ou=Employee,dc=example,dc=com",
    user-attr => "uid",
    user-attr-template => "%s",
    group => "(&(objectClass=user)(memberOf=cn=Admins,ou=Security Groups,ou=Employee,dc=example,dc=com))",
